I'm not sure where you are searching, but I wouldn't really consider the Camber to be a DH bike. At 120mm of travel it's more of a XC/AM bike.

As far as getting better...the best advice I can give is to just ride a lot and ride different trails. Also riding with people who are more experienced than you helps because you can see what they do and learn from them

+1 to riding with faster people. I met up with a friend at northstar who is tons faster than me. I tried my hardest to stay up with him mostly because i didn't want to embarrass myself too badly, But it forced me to let go of the brakes and plow through sections i normally wouldn't, and it made me so much faster. I improved more in the 2 hours I rode with that friend, then i would in a full day riding alone or with people my speed.

Just keep riding it as it is and keep trying steeper and more difficult trails as you progress and when you're ready you'll know, you know? Don't need a dedicated DH bike to try difficult things. (You'll just have to take things a bit slower, which is fine.) In fact your skills will progress just fine without it.

Still can't believe the things I rode down on my 3.8" rear suspension, 71 Deg HA XC/trail bike when I was getting started. Sketchy.... and I crashed a fair amount too, but I think I got better.

Then start saving for a more specific bike. In a year or two you'll be there.

Now excuse the dumb question but can the bike be unpgraded to be able to do DH ish stuff like whislter an other parks...cuz thats pretty much is to be able to run those types of trails

No, not really. You could ride down some of the trails in the parks, but it would not be much fun at the end of the day. That bike was not made for park riding. But, the good news is, like KRob said, it's a good first bike to learn the basics on, and on smoother trails, it is plenty fast enough (well-sorted geometry, proven suspension platform). When you progress, you'll know what kind of bike you need to get next.
